Hubble revealed the Dark Matter Web in Stunning Abel 209 Galaxy Cluster Image

Hubble Space Telescope of NASA/ESA has released a new photo of Galaxy Cluster Abel 209, 2.8 billion light-year from the US in Sitas Nakshatra. The huge cluster consists of more than 100 galaxies conducted together by gravity, but what is seen is only half the story. There is a complicated web of ignored scaffolding under the shining galaxies – hot, spread gas and a huge amount of dark substance. Although the invisible, these elements define the universe through their gravitational bridge. Hubble’s strong lens scientists enable scientists to study these invisible elements and twisted spacetime they make.

Technological progress

As NASA websiteThe new image was taken with survey (ACS) and Wide Field Camera 3 (WFC3) for Hubble’s advanced camera. The twelve exposure taken through different color filters was combined to create a full view. The final photo has a golden glow from dozens of bright elliptical galaxies in the center, as well as with some blue spiral galaxies on the edges. , Hubble survives the stain of the earth to make the distant galaxies a pinpoint-shape. In visible light, the largest galaxies appear as smooth golden colors, while the spiral galaxies shine a faint blue. Hubble displays a technical talent by merging optical and infrared data into a striking cosmic picture.

Scientific disclosure

Hubble scientists say that such images can help answer fundamental questions about dark matter and dark energy. The location between the galaxies of Abel 209 is with X-ray-hot gas and dominates the dark matter. Only 5% of the universe is a simple matter; Broadly 25% is dark matter and 70% is dark energy.

A giant cluster acts like a natural lens: its gravity slightly attacks the light from the galaxies. In the Hubble image, some unconscious background galaxies extend into curved lines. By measuring these malformations, scientists can map the total mass of the cluster (including dark matter). This lets them test the principles about how the universe has increased under the influence of dark matter and dark energy
